I'm having one issue with the install. I used the pac rp4-ch11 and I don't have any steering wheel controls beside the evic controls. No volume controls and no channel controls. I'm new to the pac adapters and had some wires left over. P.b. output. Vss output. Reverse output. Also the headphone plug coming off the control unit and a blue/yellow wire. Other than that everything else works has anyone come across this

I've looked into all the attachments at Crutchfield, but wonder if you can answer a question or two for me.

So I currently have the 130RES and DO have Sirius XM subscription (I believe it ends in July). Is there a simple adapter that would plug into the headunit for Sirius XM? Will I need TWO radio adapters?

I have the 2012 JGC Laredo (6 speaker, no sub).

I have zero experience with electronics but am thinking of doing the headunit install myself after reading up a bunch.
